Nextion is a type of intelligent touchscreen display that can be used to control and interface with various devices, such as microcontrollers and single-board computers like the Arduino or Raspberry Pi. It allows users to easily create and design their own interfaces through a drag-and-drop editor and offers real-time control and interaction with connected devices.
Nextion displays have a built-in microcontroller that runs the Nextion firmware and interpret the commands coming from the host controller (such as Arduino or Raspberry Pi) to control the elements on the display, such as buttons, sliders, text fields, gauges, etc. The host controller sends serial commands to the Nextion display and the display interpret them. Users can design their interfaces using the Nextion Editor software and then upload the generated TFT file to the display via an USB cable.
Nextion displays come in a big variety of sizes and resolutions.
Nextion offers a variety of display sizes and resolutions to choose from. The types of Nextion displays available include:
To upload code to your Nextion display, you will need to use the Nextion Editor software, which is available for free from the Nextion website. The editor software allows you to create and design your custom interfaces using a drag-and-drop editor and to generate a TFT file that can be uploaded to the display. Here are the steps to upload code to your Nextion display:
Yes, you can create animations on your Nextion display using the built-in microcontroller and the Nextion Editor software. The Nextion Editor software allows you to create and design custom interfaces with a drag-and-drop editor and to generate a TFT file that can be uploaded to the display. The editor software provides a variety of widgets and elements, such as buttons, sliders, text fields, gauges, etc. that can be used to build interactive interfaces. By using the events and actions feature in the editor software, you can create animations on your Nextion display.
For example, you can create a button that when pressed, it will change the position or color of an object. Or you can create a slider that when moved, it will change the value of a variable that controls the speed of an animation. You can also create animations using timers and conditional statements in the microcontroller.
It's worth noting that the Nextion display's microcontroller is not as powerful as a general-purpose microcontroller, so the animations may be limited in terms of complexity and smoothness, but it still can give a good user experience.
